Microsoft tests the 15-character limit of Windows Server admins’ patience

Windows Server 2016 has a bug introduced by the May 12 security update that affects servers with hostnames exactly 15 characters long, causing errors in domain controller discovery. Specifically, calling the DCLocator results in an ERRORINVALIDPARAMETER, hindering applications and tools from locating a domain controller. This issue impacts features like Distributed File System (DFS) Namespace management. Microsoft has not provided a workaround but suggests changing the hostname length. Windows Server 2016 is officially supported until January 12, 2027, with extended support options available. Despite representing only 2.2 percent of all Windows devices, it accounts for 20.3 percent of all servers. Additionally, the May 2026 security update has caused installation failures on some Windows 11 devices due to insufficient EFI System Partition size.

Windows 11’s latest patch is both the problem and the fix

Microsoft's KB5089549 update for Windows 11 addresses taskbar freezing and blank desktop displays but has installation issues due to error code 0x800f0922. The update aims to improve performance related to the taskbar and explorer.exe, with expected enhancements by May 2026. Users report taskbar freezing occurring after login or during desktop interactions. The update also creates a new folder on the user's computer. For those who successfully install it, performance improvements are noted, particularly after logging in. The update targets reliability during log-in, taskbar menu interactions, and Quick Access in File Explorer, aiming to enhance overall performance during the initial boot phase.

Microsoft confirms Windows 11’s May 2026 update is failing to install with error 0x800f0922 and outlines a mitigation for affected PCs

Microsoft has acknowledged installation issues with the May 2026 Security Update for Windows 11, specifically error code 0x800f0922, affecting devices on versions 24H2 and 25H2 after installing update (KB5089549) released on May 12. The failures occur during the reboot phase, often around 35 percent, primarily on devices with 10MB or less free space in the EFI System Partition (ESP). For consumer and unmanaged business devices, Microsoft has implemented a Known Issue Rollback (KIR), and restarting the computer may resolve the issue. For managed devices, network administrators must manually deploy a Group Policy workaround. Microsoft suggests modifying a Registry value to decrease reserved padding in the EFI partition as a potential fix, along with restarting the computer and checking for updates. A permanent solution is planned for a future Windows update.

Windows boot partition runs out of space for Microsoft’s May security update

Microsoft has acknowledged a potential issue with its May 2026 security update, which may fail to install properly due to insufficient space in the EFI System Partition (ESP). If the available space in the ESP drops below 10 MB, users may encounter a 0x800f0922 error code, leading to installation failures during the reboot phase. This issue affects Windows 11 versions 25H2 and 24H2. Microsoft has proposed two solutions: a registry edit or a Known Issue Rollback (KIR), which has already propagated to consumer and non-managed business devices. The update addresses several critical Microsoft CVEs, although there have been no reports of active exploitation.

Microsoft confirms Windows 11 KB5089549 issues due to low storage, says it’s rolling out an emergency patch to fix install errors

Microsoft has acknowledged an issue with the installation of Windows 11’s May 2026 Update (KB5089549), which has been encountering errors such as 0x800f0922, 0x80240069, and 0x80240031. An emergency server-side update is being implemented to resolve these installation hurdles. The KB5089549 update is mandatory and intended to install automatically on compatible PCs, but some users have reported difficulties, including installation stalling around 35-36%, leading to a rollback with a message stating, “something didn’t go as planned. Undoing changes.” Investigations reveal that installation failures are particularly affecting devices with limited EFI partition space, with error code 0x800f0922 indicating insufficient free space and potential conflicts with third-party files. The EFI System Partition (ESP) typically occupies no more than 100MB and can become congested due to leftover files, causing installation failures when available space is low. Users with less than 10MB of free EFI storage may face additional complications. A PowerShell command can be used to check EFI storage status. Microsoft has advised users to consider increasing the size of the ESP by modifying the Windows Registry, although the recent server-side update may have already addressed the issue. The Known Issue Rollback (KIR) has been implemented, automatically propagating the resolution to devices. Users are encouraged to restart their devices to expedite the application of the fix, and there are no additional bugs reported.

Microsoft confirms April Windows updates cause backup failures

Microsoft has acknowledged that the April 2026 security updates have disrupted the functionality of various third-party backup applications using the psmounterex.sys driver, raising concerns among users. The issue primarily affects software leveraging the Volume Shadow Copy Service (VSS) snapshots, leading to failures due to VSS service timeouts. Notable impacted products include Macrium Reflect, Acronis Cyber Protect Cloud, UrBackup Server, and NinjaOne Backup, used on Windows 11, Windows Server, and Windows 10 devices. Disruptions can manifest as failures to mount backup image files, errors or timeouts when browsing or restoring from backup images, and error messages related to VSS timeouts. Microsoft updated its support documentation to clarify that the April updates included a security hardening change that added psmounterex.sys to the vulnerable driver blocklist to protect against a high-severity buffer overflow vulnerability (CVE-2023-43896). Affected users are advised to upgrade to newer application versions with updated drivers and not to uninstall or pause the security update. Users can check if the Microsoft Vulnerable Driver Blocklist is blocking a driver by looking for Event ID 3077 in the Code Integrity Operational log. Additionally, Microsoft has alerted users that some Windows Server 2025 devices may boot into BitLocker recovery mode after installing the KB5082063 update and has issued out-of-band updates to address installation failures and restart loops affecting Windows Server systems after the April 2026 updates.

April KB5083769 Windows 11 update causes backup software failures

The KB5083769 security update released in April 2026 has disrupted the functionality of various third-party backup applications on Windows 11 versions 24H2 and 25H2, primarily due to issues with the Volume Shadow Copy Service (VSS). Affected applications include Acronis Cyber Protect Cloud, Macrium Reflect, NinjaOne Backup, and UrBackup Server. Users have reported receiving an error message indicating that backups have failed due to VSS timeouts. Acronis has acknowledged the issue, stating it affects both Windows 11 Pro and Home editions, and warns of potential broader system issues. A temporary solution involves uninstalling the KB5083769 update or pausing Windows updates. Additionally, Microsoft has issued out-of-band updates for critical issues affecting Windows Server systems and warned that some Windows Server 2025 devices may encounter BitLocker recovery prompts after installing the KB5082063 update.
